To all whom it may concern.-

Be it known that I, ADONIRAM J. COLLAR, a citizen .of the United States,residing at Yreka, in the county of Siskiyou and State of California,have invented new and useful Improvements in Water Grate-Valves, ofwhich the following is a specification.

My invention relates to an improvement in devices for controlling theflow of water in pipes, and is of that class known as the straightwaygate-valves.

It consists in the combination of mechanism and in details ofconstruction, which will be more fully explained by reference to theaccompanying drawings, in which- Figure 1 is a central vertical sectionof my device. Fig. 2 is a plan view of the casing, showing the gatemechanism. Fig. 3 1s .a vertical cross-sectional view.

My present invention is designed to provide improvements in theconstruction and operation of gate-valves which are designed :to bemoved transversely across the path through which the water passes.

A is the casing, of any suitable or desired shape adapted to contain thegate mechanism. This case has openings 2 and 3 at opposite sides. Theseopenings are in line with the conducting-pipes through which the waterflows. Within this casing is a shell 41, which -is fitted to slide upand down trans versely of the path of the water. The upper part of theshell has an opening within which is loosely fitted a nut 5, and throughan opening in the top of the shell passes a stem 6, which screws intothe nut, and by reason of the large size of the opening the nut isloosely movable with relation to the block.

The shank of the screw-threaded stem extends upwardly and has a fixedcollar or flange 8, turnable in a chamber in the yoke 7,

so that when the stem is rotated it will not be advanced in eitherdirection, but by reason of its threaded end it serves to advance theshell which carries the valve, so as to open or close the latter. Theyoke also serves as a guide to maintain the stem in proper alinement.

The casing is here shown with one of the sides inclined, and the valve 9is closable against this side. The opposite side of the casing may bevertical, and a roller 10 is adapted to travel against the interior ofthis vertical side and between it and the shell 4., which carries thevalve 9, so as to maintain the valve in proper position to close whenthe shell is depressed. Ghannels are made upon each side, within whichthe roller travels.

The shell carries a projecting plate which contacts with the top .of theroller when the gate has been closed. When the shell is raised to openthe gate, the roller, with its ends traveling in these guide channels,will roll against the side of the casing and against the adj acent sideof the shell, thus providing for an easy antifrictional movement oftheshell.

The shell has upon each side projecting ribs, as at 12, and these ribstravel against guides 13, which are fitted within the casing andparallel with the side thereof against which the roller 10 travels. Thusthe shell is caused to move in the straight line of its travel and toretain its true vertical position during its movement.

Fixed to the shell upon each side are elastic arms 14. These arms havestraight edges projecting alittle beyond the face of the shell which iscontiguous to the roller 10 and which isof sufficient width to form asuitable bearing between it and the inner side of the casing, where theroller travels, and this sprin pressure serves to retain the ribs 12 ofthe s ell in contact with the guides 13, and thus insure an even steadymove ment of the shell in its rise and fall. They also, by reason oftheir pressure against the roller, will cause it to roll when there isno water-pressure against the valve to insure such rolling contact.

The valve 9 has a shank 15 extending into an open slot in the side ofthe shell which is adjacent to the valve, and this shank is slottedvertically. The walls of the shell, which are in line with the slot ofthe shank, are similarly slotted, and a roller 16 passes through theslots of the shell and the shank and forms a bearing which allows thevalve, when closed, to remain seated against its incline face until theshell has been raised sufliciently to reduce the wedge-like pressure bywhich the valve is firmly closed when the shell has been depressed tothe lowest point. This reduction in pressure takes place by the raisingof the wedge-shaped shell, and thus releases the valve, so that when theroller has reached the end of its travel in the slots a direct pull willbe exercised by the upwardly moving shell to lift the valve and exposethe passage through which the water may fiow. When the shell isdepressed to close the valve, the valve will be moved down with theshell until it has covered the water pasroller in the same 1 Lil sagethrough its seat, and the further movement after the valve has beenarrested by a stop on the inside of the shell, as shown at 17, willcause the wedge -shaped shell to act against the roller 16 until thevalve is forced against its seat and made sufliciently tight. The lowerend of the shell carries a projecting rib or lugs, against which theroller 10 contacts to limit the upward movement of the shell bypreventing further rotation of the anner that the contact of the rollerwith the projection or lug 11 limits the downward movement of the shell.

I have shown in the present construction only a single valve, and thismay either close against the flow of water or in the directiontowardwhich the water is flowing, the operation of the parts heredescribed being the same in either case.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination of a casing having an inclined seat, atransversely-slotted shell or carrier, means by which it may bereciprocated within the casing, a disk with a vertical slotted shankentering the shell or carrier, corresponding slots made in said shell, aroller passing through the slots of the shank and shell, vertical guidesfixed within the casing, ribs upon the shell adapted to travel againstsaid guides, and a roller-bearing between the opposite side of thecasing and the shell.

and the interior of the casing, elastic bearings carried by the shellbetween which and the inner face of the casing, the roller rotates, anda valve carried by the shell and closable against the inclined seat.

3. The combination of a casing having an inclined valve-seat upon oneside, a substantially vertical face upon the -opposite side, guideswithin the casing parallel with the vertical face, a shell or carrierslidable against the guides, elastic arms fixed to the shell andprojecting beyond its vertical face, and a roller revoluble between saidarms and the said vertical face of the casing, whereby the shell ismaintained in contact with the guides, and a valve carried by said shelland closable against the inclined seat.

4. The combination of a casing having an inclined seat upon one side anda vertical inner face upon the opposite side, guides within the casingparallel with the vertical face, a-

shell or carrier slidable against said guides, a roller revolublebetween the vertical face of the casing and the corresponding face ofthe shell or carrier, and elastic means by which the shell is maintainedin contact with the guides, a valve carried by the shell and closableagainst the inclined seat, and means by which the shell is raised ordepressed, said means comprising a nut fitting loosely in the socket orchamber at the top of the shell, a screw-threaded stem turnable in thenut, said stem having a flange or collar and a yoke through which thestem passes and Within which the stemand collar are turnable withoutadvancing.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
